Thursday, a study that refutes the Mexican Government's version of the Ayotzinapa case was presented. The government claims the students were incinerated by criminal gangs at the Cocula garbage dump. A report on the forensics findings regarding the 43 missing students will be presented by researchers of the National Autonomous University of Mexico (UNAM) and from the Autonomous University of Nayarit (UNAN). The head of the Research Unit of UNAM's School of Forensic Science rejected the possibility that more than 40 bodies burnt in tire bonfire could have been totally pulverized. Clayton Conn has more for us from Mexico. teleSUR
